  • Patent number: 4821746
    Abstract: The present invention provides a bar-like article supplying apparatus in a hopper, and more specifically to an apparatus for supplying bar-like articles such as cigarettes or filter plugs to the hopper, wherein a bottom lid comprises a plurality of small bottom lids obtained by dividing the bottom lid in a radial direction of bar-like articles, whereby these small bottom lids are rotated in a radial direction of the bar-like articles to make the moving stroke of the bottom lid small to miniaturize the entire apparatus and bar-like articles are supplied preferentially from a depressed portion in the upper surface of the bar-like articles within the hopper, thus eliminating a disturbance of the bar-like articles.

  • Patent number: 4661034
    Abstract: A method and apparatus for supplying bar-like members such as cigarettes and filter plugs, in which a bar-like member containing box is lifted at a supplying position which supports the containing box in an inverted condition; and a pusher is operated to feed the bar-like members instead of a conventional hopper construction which stores bar-like members and allows them to drop from same, whereby the speed of the supplying operation is increased and a smooth supplying operation is assured without causing disordered orientation of the bar-like members.
